I didn't tear up the first time I saw the movie, but curiously I developed a lump in my throat the second time I saw it. Maybe because it was easier to sit back and absorb the story when I knew what was going to happen.

Me too. I saw twice until now and just got emotional on the second one. And even knowing what gonna happening next, I was tense in some parts. For example, when Blake returns to the hospital to rescue Gordon, I already knew what happened next, but I was mentally screaming: "Oh my God, they gonna kill Gordon!". This is totally Nolan's merit, because the tension was so well done.
